The process appears to be continuous, only stopping when Firefox is shut down with Ctrl + Alt + Del or by stopping the tabs from loading with the red X next to the Refresh button. I had no rpoblems opening PDF files before my dad updated Firefox (I'm not sure with what, but it's been a few weeks). This is his computer so I'm sorry that I can't provide more detailed information. Reproducible: Always Steps to Reproduce: 1. Download PDF file 2. Click to open Actual Results: Opens multiple blank tabs in an unending process. Last count was over 400 before I managed to close Firefox. If Firefox is already open when opening the PDF, it simply adds the tabs to it. Expected Results: The PDF file should have opened like normal.

Everything went as expected. No problem. No surprise. XP SP2 here.
=> Incomplete. Did not hear back from the reporter if Firefox was configured to open pdfs.
